More Information
Summary:The invention discloses an automobile silencer, and relates to the technical field of automobile silencer production. The automobile silencer comprises a shell provided with an air inlet pipe and an air outlet pipe. The inner space in the shell is divided into a first cavity, a second cavity and a third cavity by two separating boards with holes in the air inflow direction. The tail end of air inlet pipe is blocked, and the air inlet pipe penetrates through the first separating board and the second separating board sequentially and stretches into the third cavity. Pipe sections with holes of the air inlet pipe are both arranged on the second cavity and the third cavity. A circle of through holes which are circumferentially distributed of the air outlet pipe is formed in the pipe wall of the second cavity. Compared with the prior art, the automobile silencer can improve the stability of the silencing performance effectively.
